Optical investigation of SnS2 single crystals

The optical properties of the layered compound SnS2 have been studied. Reflectivity spectra were measured at room temperature, in the energy region 1.8–5.6 eV. Optical transmission measurements were carried out in the temperature range 13–300 K, in order to evaluate the energy gaps and their temperature dependences. The spectra of the optical constantsn, κ, ɛ1 and ɛ2 versus photon energyhν have also been presented.
